2 Claims.

My invention relates to improvements in shields adapted to be applied to windows and like closures in dwellings and other heated quarters for providing insulating air spaces for the glazing in such closures.

Such shields are desirably used to conserve heat and also to prevent moisture in the air from condensing on the inner surfaces of the glass in the closures, whereby visibility through the glass i0 and the facility thereof for the transmission of light therethrough will remain unimpaired. and the danger of dripping from excessive accumulations of condensate on the glass will be avoided.

An object of the present invention is to provide x a compact and slightly insulating shield of simple,

durable and comparatively inexpensive construction readily adapted to be applied to a Window or similar closure.

More specifically, it is an object of my inven- 00 tion to provide a shield of the present nature, having a relatively flat frame endlessly grooved edgewise, internally thereof to receive the marginal portion of a glass panel and endlessly grooved laterally thereof to receive a resilient gasket for providing a tight seal between the shield and the glazed closure to which it is applied.

Another object of the invention is to provide a glazed insulating shield, as above, having frame members and simple, though effective means 00 housed within the gasket receiving groove of the frame and adapted rigidly to connect the frame members together.

A feature of the invention resides in the utilization of the frame connecting means for the 35 purpose of holding the sealing gasket within its groove.

With the foregoing and other objects in view, which will appear in the following description, the invention resides in the novel combination t0 and arrangementof parts and in the details of construction hereinafter described and claimed.

In the drawing, Fig. 1 is a fragmentary perspective view illustrating a corner portion of an insulating shield embodying my invention, the

45 same being shown as applied to the corner portion of a metal window sash; Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is a rear elevational view illustrating a corner portion of the frame of the shield; Fig. 4 is a sectional 5U view taken on the line 4-4 of Fig. 3, and Fig. 5 is a detail perspective view illustrating one of the connecting members employed in securing the frame bars together.

Referring to the drawing, wherein similar parts M throughout the several views are designated by (ci. lss-c4) similar reference characters, it will be observed that the illustrated embodiment of my inven-l tion includes a frame A and a glass panel II) supported in said frame. Fig. 1 shows this shield as applied to a metal window sash B having a 5 formed by extrusion. Each of these similar bars I5 comprises dual channels, each consisting of a web and legs, one channel opening edgewise of the bar and the other channel opening laterally thereof. One leg I6 of the edgewise opening 20 channel and the web Il of the laterally opening channel lie in continuation, one of the other, and form the front face of the bar. 'I'he member I8 is common to both channels, and constitutes the web of the edgewise opening channel and one leg 25 of the laterally opening channel. 'I'he second leg of said laterally opening channel is designated by the reference numeral I9, while the secondleg of the edgewise opening channel is designated by the reference numeral 20.

The bars I5 of theframe A are mitered at their ends so that when they are put together the edgewise opening channels of said bars provide an internal groove 2I perimetrically of the frame and thelaterally opening channels provide a lateral perimetrical groove 22 at the rear of the frame. The internal groove 2l receives the marginal portions of the glass panel I0 and also glazing compound 23 used in setting said glass in said frame, under-cuts 24 being provided 40 in the inner sides of the channel legs I6, 20 to keep such compound in place.

The bars I5 of the frame are rigidly fastened together by means of tie-plates C contained within the bar structures. These tie-plates are angular in cross-section, each having legs 25 and 26, and, in the form illustrated, said tie-plates have reaches disposed at right angles with respect to each other to conform with the right angular relationship of the bars I5, in the rectangular frame A. Said tie-plates C are received in the laterally opening groove of the frame and the leg 26 of each thereof lies flatwise against the webs II of the outer channels of adjacent bars I5. while the leg 25 lies against the legs I9 of said 55 channels, said leg 28 being of such width as to completely traverse the groove in which the tieplate is placed, whereby the edge 28a of the leg 28 bears against the lar members I8. `Each tiel plate C is secured in place and to adjoining frame bars I5 by means of fastening screws 21 which pass freely through the legs I9 of said bars and are threaded in the leg of the tie-plate.

A sealing gasket 28, endless in form. or consisting of a number of strips, made from sponge rubber or other suitable resilient material is seated in the laterally opening groove of the frame A, said gasket being received only in part Within the outer channels of the frame bars I5, the remainder thereof projecting considerably beyond the rear plane of the frame A.

The fastening screws 21 are relatively long and are screwed not only through the legs I9 of the frame bars I5 and the legs 25 of the tie-plates C, but are also screwed a substantial distance into the portion of the sealing gasket 28 disposed within the outer channels of said frame bars. Thus, in addition to fastening the frame bars together, through said tie-plates C, said screws 21 further serve to hold said sealing gasket 28 within its groove in the frame.

In the application of the shield to a closure, as shown'in Fig. I, the frame A of the shield is placed against the frame B of the closure with the gasket or sealing strip 28 abutting against the closure frame. Any suitable means may be employed for holding the shield in place against the closure with the gasket 28 under compression to create a tight seal between shield and closure and thus provide` an eilicient insulating dead air space between the glazing of the closure and shield. I have shown simple means for clamping the shield to the closure frame II, said means consisting of a number of identical clips 29, each consisting of a strip of metal with the terminal portions thereof reversely bent to form a lug 30 and an ear 3l at the opposite ends of a shank 32. The shank 32 traverses the outer edge or leg I9 of a frame bar I5, the ear3I on said shank overreaching and engaging the face of the bar. A clamping screw 83 passing through an opening 34 in the lug 38 and threaded into the frame II of the closure serves to pull the shield A against the closure frame and rmly hold it in place against said frame.

The construction of my shield readily adapts its production to meet the various requirements in practice and enables the manufacture thereof to be carried on economically. The shield may be applied to a closure properly and easily, even by a novice.

Due to the construction of the frame bars, the laterally opening groove in the frame is comparatively deep even though the frame is relatively thin. This substantial depth in the laterally opening groove admits of the reception therein of securing means for effectively fastening the frame bars together and, further, admits of the 5 reception in said groove of a gasket which is relatively thick and highly compressible.

Changes in the specific form of my invention, as herein disclosed, may be made Within the scope of what is claimed without departing from the 70 spirit ofl my invention.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

l. A shield adapted to be disposed against a glazed closure to provide an insulating air space for the glazing therein, said shield including a panel of glass and a frame of separate, similar bars of integral, dual channel s construction mitered at their ends, each bar having an inner channel opening edgewise thereof and an outer channel opening laterally thereof, each channel of each bar having a web and legs, the web of one channel and a leg `of the other being a single member common to both, the frame bars being adapted to be associated with the panel and to be thereby relatively aligned upon application thereto with the edgewise opening channels of said frame barsreceiving the marginal portions of said panel, said laterally opening channels of the frame bars forming an outer groove in the frame, tie-bars for connecting the frame bars together, said tie bars being disposed within the outer groove in said frame and being angular in cross-section, one leg of each tie-bar completely traversing said outer groove and lying against the webs of its respective laterally opening channels and the other leg lying against the outermost legs of such channels, a resilient sealing gasket partially contained within the outer groove of the frame and projecting from said frame to provide a sealing member for contact with the closure, fastening screws for securing the tie-bars to the bars of the frame, said screws passing through the outermost legs of the laterally opening channels and the legs of the tie-bars lying thereagainst, said screws being projected into that portion of the resilient gasket contained within the outer groove of the frame and serving to retain said gasket seated within said groove.
